I have about 500 rounds through a new glock 26 gen 5 that still jams with 115 grain Winchester ammo. When I shoot 147 grain, the gun doesnt jam. I know 115 isnt full powered ammo, but I didnt think it mattered with a Glock. I kinda have a sorta different impression of Glock now.

Does anyone else experience this problem? I heard the rsa is tight, but I shot a g43 with the same 115 grain ammo and not one malfunction.

Nope. Mine runs like a champ regardless of ammo.

 

Is it factory 115 gr or reloads?
I don’t have the 26 but have a 19 and no issues with any ammo.

 

its factory Winchester 115 grain. I was thinking about contacting Glock, but I figured they would just tell me its normal.

 

My experience with 26s - several Gen 3s (mine and my wife's) and several Gen 4s (mine and my dad's) and my friends Gen 5 has shown them all to be 100% reliable with any factory ammo that we have shot - mostly 115gr FMJ for practice ammo too.

Winchester 115 FMJ white box is a little underpowered though - in my experience, and the quality control is not as good as some other 115 fmj that I have shot (several bad primers and one oversized case in the last year).

 

Get someone else to shoot a few mags they it and see if it happens with them.

 

These Gen5 G26 pistols are working for some folks I personally know. When I shopped for them, however, there were none to be had. The first G26 pistols that appeared, when the pipeline opened again, were Gen3, so, that is what I bought, and so I cannot offer advice based upon personal Gen5 G26 experience. (I had sold my totally-reliable Gen4 G26, which had been my ankle-holstered back-up gun, to one of my former rookie trainees, when compact Glocks started vexing my right thumb/hand/wrist arthritis. I did not regret trading-away my three G19 pistols, but eventually realized that I still really needed a G26, even if I will never be shooting it right-handed.)

Generally speaking, however, let someone who knows how to run a G26 test-fire a meaningful sample of ammo through your G26. If it runs, for them, well, the weapon is within specs, in which case an alteration of technique may be needed. And, importantl;y, not every small auto-pistol is suited for every user’s hands.

 

The only issue I have ever had with my Gen 5 G26 was running a 12 round PMag. If I loaded the mag, chambered a round and then topped the magazine back off, the 1sst round in the magazine would fail to feed. None of the factory Glock mags from the flush G26 mags up to the 33 round Glock mags would experience this. As long as I do not top the PMag off, the magazine functions fine. Needless to say, it is used as a range magazine only.

 

I am using factory 10 round mags. If it is limp wristing, I wonder why I can shoot a g43 with this same ammo and not get any malfunctions. Maybe because the g43 slide is thinner and lighter, idk? I would like to try a 365 to see if I experience these malfunctions. I know smaller guns are more susceptible to limp wristing. I actually appreciate full size handguns now, but just cant ccw them.

 

The gun should function properly 100% of the time with any 9mm ammo. I'd maybe contact the place you bought it, or the manufacturer.

 

Tear gun down. Scrub clean. Lube and reassemble. Test again.

Run SN by Glock for any potential recalls or upgrades.

 

I've had a Glock 23 for 30 years. Never had a problem with any ammo. Never had a jam or other malfunction. Not once... and, I'm sad to say, because of this, I didn't always keep it in well-maintained condition. I felt I didn't need to. It always worked, regardless.

Are there functional differences with the newer models that can cause these problems, or is this just a fluke?

 

I have a bunch of Glocks that work with everything. Ejection patterns can sometimes get wiffy with light loads but no other problems. My Gen 3 26 is probably the best of them all around. If it was me, I would just avoid the ammo that doesn't work and keep chugging along. Good luck.

 

Just a tiptoe off the beaten path . . . My G30 has balked only on one load--my attempts to reload 200-grains SWCs. Had a very bad time going into battery no matter how I set the COL and adjusted the HP-38 powder throughout the recommended load range. Did some digging and found others had the same issue with SWCs. Dumped that style bullet and never looked back.

 

Try a truncated profile bullet instead of the swc. They are similar, but enough difference to make a difference.
Very similar profile to a Hornady XTP. Also, crimp has to be good. I bought a 45 Auto gauge for the plunk test, and found that I had to run the crimping operation separate from the seating. Maybe due to using mixed brass, and some would not chamber.
Ran the crimp separately and they all feed perfect in the G21.

 

Frankly it's hard to imagine a Glock having problems with any ammunition, unless it is the ammo's or the shooter's fault . If it is the gun, that would be very unusual. Find a good and Glock-qualified armorer and have him see if there are any problems with your G26. You shouldn't be having problems with this gun.

 

Owned and shot many Glocks over the years. None were the G26. But all of them went bang with extremely rare failures. Except the G42. None of those would run.

 

Never had an issue with my G26. It has been flawless.

 

My gen 4 G26 eats any ammo flawlessly

 

Not a Gen 5, but a recently purchased Gen 3 G26 USA made gave me similar problems. Would sometimes not cycle with Blazer brass 115 grain, but fine with Fed Classic 9bp.

It simply needed to be broken in. Glock recently upgraded the recoil spring to stronger weight. Plus, the slide to frame fit on this G26 was tight. So, I just hand cycled the slide not letting slide slam home. Did this a couple of thousand times - yes, I counted and kept track. Lubed every 500-700 hand cycles. Works fine now with Blazer Brass. Good luck.

 

Glocks have a history of being reliable. The longer action Glocks seem to be able to run lighter ammo better than short Glocks.
